TOOLS FOR RAILWAY AIR BRAKE HOSE CONNECTIONS Filed on. 14, 1957 United States a 2,999,310 TQOLS FOR RAILWAY AIR BRAKE HOSE CONNECTIGNS Wiley S. Pope, 2426 Ave. U Ensley, Birmingham 8, Ala. Filed Oct. 14, 1957, Ser. No. 689,879 1 Claim. (Cl. 29-270) This invention relates to tools for railway air brake hose connections. It has for its main objects to provide such tools that will be highly satisfactory for the purpose intended, simple in structure, cheap to manufacture, easy to keep in working condition, and extremely durable.

A further object is to provide such tools adapted for use with safety Without the danger of the user having to go between the ends of railway cars in order to connect and disconnect the joints of air brake hose.

Other objects and advantages will appear from the drawing and description.

By referring generally to the drawing it will be observed that FIG. 1 is a general view of the two ends of hose of a railway air brake with connecting means attached and parts of the tools of the present invention mounted in position for use in connecting or disconnecting the metal parts that hold the hose ends in place for use; FIG. 2 is a perspective view of the main tool; and FIG. 3 is a plan view of the holding tool.

Similar reference numerals refer to similar parts throughout the several views.

Referring to the drawing in detail it will be seen that the main tool comprises a metal rod forming a handle portion 1, a shank portion 2, an extension 3 that is partly curved, two extensions 4 and 5 formed substantially U shape. The holding tool comprises a'metal rod having a handle portion 6, and a curved end portion 7 formed substantially as a hook. The main tool in use fits upon the hose end 8 and metal part 9. The holding tool in use hooks around the other metal part 10. In use the parts of hose and metal connectors hang downward and form a half circular position between the ends of cars in a train. At present a trainman goes in between the car ends to connect or disconnect the air line joint. With the tools of the present invention the trainman uses the holding tool to pull the joint out from between the car ends as far as its curved condition will permit, and

Patented Sept. 12, 1961 then places the main tool extension portions upon the joint and manipulates the handle of the main tool to disconnect the joint. To connect the joint both tools are used to get the parts in position for connecting.

The tools may be made of any material suitable for the purpose, but I prefer to use a good grade of metal rod; also the tools may be made in different sizes and capacities.

While I have shown and described the preferred embodiment of my invention, I do not wish to limit same to the exact and precise details of structure, and reserve the right to make all modifications and changes so long as they remain within the scope of the invention and the following claim.

Having described my invention I claim:

A tool for railway air brake hose connections, comprising a metal rod, said rod having one end formed as a T shaped handle, its other end portion being bent slightly out of line with the shank portion leading from the handle, its bent portion being formed with three integral extended portions, two of said extended portions being at the extreme end of the rod, being substantially U shaped and extending substantiallyperpendicular to said other end portion, the other extended portion being positioned at the point on the rod where it starts to bend out of line and extending outward from the rod in the same direction as that of the U shaped extended portions.
